Background:

Tubulysin H is a highly cytotoxic peptide isolated from the myxobacterial species Archangium geophyra and Angiococcus disciformis[1]. Tubulysin displays extremely potent cytotoxic activity in mammalian cells, including multidrug-resistant cell lines, with IC50 values in the lower nanomolar range[2]. Tubulysin H is a cytotoxic activity tubulysin which inhibits tubulin polymerization and leads to cell cycle arrest and apoptosis[3].
